Inside Alyson Hannigan And Alexis Denisof's Relationship

Wesley and Willow may have never shared an on-screen romance on "Buffy the Vampire Slayer," but Alexis Denisof and Alyson Hannigan, who played the characters, have been married since 2003. While the chemistry between the two was undeniable even during their "Buffy" days, their bond only grew stronger as they continued to work together, co-starring on episodes of "Angel" and "How I Met Your Mother." Hannigan told E! News Denisof was initially reluctant to date a co-star: "I was trying to pursue him, but he said he didn't want to date somebody he was working with. But we developed a great friendship." It was a great friendship that turned into something more, seeing as the two started dating two years after they initially met. 

The pair made it official when they tied the knot in 2003 in a ridiculously fun, three-day soiree at an exclusive resort near Palm Springs, where they had gone on one of their first trips together. The festivities included a photo booth, choreographed dance routines and a trampoline. Their first dance as a married couple was a nod to the show that started it all. They danced to a medley of "Over the Rainbow" and "No Tengo Dinero" by Los Umbrellos, per E! News. The significance? "No Tengo Dinero" is the same song Hannigan and Denisof's characters first danced to on the show — how cute is that? 

Now, multiple decades and two children later, Denisof and Hannigan remain one of Hollywood's unbreakable power couples. So what's the secret to their long-lasting love? 

Alyson Hannigan and Alexis Denisof have a close-knit family

With two small daughters, Satyana and Keeva, born in 2009 and 20012, respectively, it's no wonder Alyson Hannigan and Alexis Denisof are still kids at heart. Both girls were born at home, with Hannigan eschewing a hospital visit for a midwife. She dished to Yahoo News! that she had asked Satyana if she wanted to watch Keeva being born. However, the then-3-year-old declined in favor of playing with her Barbies. 

Hannigan believes that the birth of their second daughter not only helped them to become better parents, but also better partners."There's such a huge learning curve, especially with the first baby," the actor told the media outlet. "Everything seems like, 'If I don't change this diaper correctly, she won't go to college.' My advice is, know that the time does go by fast... it's a huge roller coaster, it's the hardest thing and most rewarding thing. Bear with it and communicate. Our second child was 2 by the time Alexis and I figured out how to be a couple and parents."

Alyson Hannigan and Alexis Denisof keep the romance alive

Alyson Hannigan and Alexis Denisof may have a busy life balancing two kids and two successful Hollywood careers, but that doesn't stop them from keeping their romance alive. In October 2013, the couple marked a decade of marriage by renewing their vows. On July 28, 2013, Hannigan took to Twitter to share the events that led to the vow renewals in the first place, "My hubby @AlexisDenisof surprised me with the most romantic day of my life yesterday! Which included another proposal & ring! I said YES!

She later added that she was also excited to have her kids be a part of the ceremony this time. According to the Daily Mail, the couple and their daughters enjoyed an intimate sunset ceremony in Hawaii. Satyana played a pretty big role in the vow renewal, not only acting as Hannigan's flower girl, but also her maid of honor.

Alexis Denisof is Alyson Hannigan's best friend

It's the best of both worlds for Alyson Hannigan when it comes to her relationship with Alexis Denisof. Not only is "The Guardians of the Galaxy" star her husband, but he's also her best friend. In fact, the "How I Met Your Mother" actor credits this friendship as the foundation for why their relationship has lasted so long. When asked how they keep their romance "solid" by YourTango, she declared, "We're best friends. He's my partner and I wouldn't want to do this with anyone else." That was back in 2013 and the statement still holds true nearly 10 years later.

In October 2023, the couple celebrated their 20th anniversary. Hannigan shared a sweet post to her husband of 20 years, calling him — you guessed it! — her best friend. "Happy 20th wedding anniversary to the most incredible husband @alexisdenisof," she wrote. "Thank you for being my best friend, the best father, the greatest chef, silly comic relief and so much more. I love sharing life with you!" Hannigan and Denisof tied the knot in 2003 and have created a life together filled with kids and wonderful memories. Unlike many relationships in Hollywood, the couple's romance remains strong after all these years.

Alexis Denisof supports Alyson Hannigan in everything she does

From her acting career to "Dancing With the Stars," Alexis Denisof has supported Alyson Hannigan in every aspect of her life. Hannigan joined the cast of the dancing competition show back in September 2023, and as viewers know, the show can take a toll on a celebrity's personal life, but luckily, Hannigan has had some help.

When speaking with People, the "How I Met Your Mother" star revealed that Denisof has been an incredible husband during her time on "DWTS." She shared, "He's been so supportive and I'm not surprised, but I'm super appreciative. He is that guy. He's always been a hands-on dad and he's made so many sacrifices for us." From cooking to bringing her ice after a tough week, Denisof is Hannigan's right-hand man. The actor has not only shown her appreciation for her husband through words, she also dedicated a dance to Denisof.

In October 2023, the contestants on "DWTS" were asked to choose a significant event in their life that would inspire their dance, and Hannigan chose her wedding to Denisof. She shared a post on Instagram explaining, "Tonight we celebrate my most memorable year... 2003: the year I married my husband and our happily ever after began." Denisof and Hannigan are truly couple goals as they support and love one another in all their ventures.
